Answer 1

6.02×10^25

Answer 2

The correct answer is:

6.02 × 10^25

Answer 3

The correct answer is 6.02 × 10^25. To calculate the number of molecules in 100 moles, Carlos used Avogadro's number, which is approximately 6.02 × 10^23 molecules per mole. Since Carlos has 100 moles, he multiplied 100 by Avogadro's number to get the total number of molecules. In scientific notation, this value is written as 6.02 × 10^25.
